Debian: New klisa packages fix buffer overflow

iDEFENSE reports a security vulnerability in the klisa package, that provides a LAN information service similar to "Network Neighbourhood", which was discovered by Texonet. It is possible for a local attacker to exploit a buffer overflow condition in resLISa, a restricted version of KLISa. The vulnerability exists in the parsing of the LOGNAME environment variable, an overly long value will overwrite the instruction pointer thereby allowing an attacker to seize control of the executable. Fixed packages are available from security.debian.org.
